Metric Conversions for Nursing Questions

Question 1 of 5

What does the prefix 'Tera' refer to?

Correct Answer: A

Rationale: The prefix 'Tera' corresponds to the value of 10^12. This can be understood by knowing that the International System of Units (SI) prefixes are based on powers of 10. 'Tera' comes after 'Giga' (10^9) and before 'Peta' (10^15). Therefore, the correct choice is A. Summary of other choices: B: Incorrect because 'Giga' represents 10^9. C: Incorrect as 'Peta' represents 10^15, a higher value. D: Incorrect because 'Mega' represents 10^6, a lower value than 'Tera'.

Question 2 of 5

How many centimeters are in 4 meters?

Correct Answer: B

Rationale: To convert meters to centimeters, you multiply by 100 (1 meter = 100 cm). So, 4 meters x 100 cm/meter = 400 cm (Choice B). Choice A (40 cm) is incorrect as it represents 0.4 meters. Choice C (4 cm) is incorrect as it corresponds to 0.04 meters. Choice D (0.4 cm) is incorrect as it is 0.004 meters. Therefore, the correct answer is B (400 cm) as it accurately represents 4 meters in centimeters.

Question 3 of 5

What is the equivalent of 500 milliliters in liters?

Correct Answer: B

Rationale: To convert milliliters to liters, we need to divide by 1000 since 1 liter is equal to 1000 milliliters. So, 500 milliliters divided by 1000 equals 0.5 liters, making choice B the correct answer. Choice A (0.05 liters) is incorrect as it is one decimal place off. Choice C (5 liters) and choice D (50 liters) are both significantly higher values and do not align with the conversion factor from milliliters to liters.

Question 4 of 5

What is the conversion factor from milliliters to liters?

Correct Answer: A

Rationale: The conversion factor from milliliters to liters is 0.001 liters. This is because there are 1000 milliliters in 1 liter. To convert milliliters to liters, you need to divide the number of milliliters by 1000. Therefore, 1 milliliter is equal to 0.001 liters. Summary: Choice A (0.001 liters) is correct because it accurately reflects the conversion factor. Choices B, C, and D are incorrect as they do not align with the correct conversion ratio of 1 liter being equivalent to 1000 milliliters.

Question 5 of 5

What is 0.5 liters in ml?

Correct Answer: A

Rationale: To convert liters to milliliters, you multiply by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters is equal to 0.5 x 1000 = 500 ml. Choice A (500 ml) is correct. Choices B, C, and D are incorrect because they do not follow the correct conversion factor of 1 liter to 1000 milliliters. B (50 ml), C (5 ml), and D (0.5 ml) are not the correct conversions for 0.5 liters.
